I think some aliens was playing with this ball in the space but somehow its fell into the earth and just smashed into the belly of this poor liliput guy and thats the reason please somebody call the
museam to take the baseball and to find some new thing about the alliens but dont care of him he is now on to the way of sky

Think somehow there was a machine which makes things bigger and this person was very cheeky with who he was playing against so they had to make sure he lost otherwise he might have a chance to win so they secretly made this. Device and when they threw the ball it suddenly became bigger and quickly ran away as the poor man became crushed ..
Lesson to be learned : never be to cocky
